From Alja, Bertrand and Matevz - merged branches/dev/fireworks 22550:23082.
Major changes imported by this merge are:
gl/
====
- reorganization of scene rendering in TGLViewer - render opaque
objects from all scenes first, then all transparent ones;
- improve saving of images from the GL-viewer so that the dialog boxes
and other windows do not result in black areas on the saved image;
- improved management of FTGL fonts accross GL contexts.
eve/
====
- new classes for visualization of calorimeter data in lego mode;
- allow fixed scale beyond given radius for fish-eye projections.

From valeriy:
o TASImage.h, TASImage.cxx, TImage.h
new method was introduced GetVecArray
Returns a pointer to internal array[width x height] of double values [0, 1]
This array is directly accessible. That allows to manipulate/change the image.
o TASImage::GetArray
Fix to return correct array (previously it was truncated when
x, y shift position were not zeros).
o TASImage::GetPolygonSpans
Fix segv when producing images from some Rene's macro.
o fix segv. when image is drawn in canvas and canvas resized.
o TAttImage.cxx
For "Pretty Palette with a Spectrum Violet->Red" set
white color to zeros.

- From V.Onuchin:
TImage::PaintImage:
extend this method to allow to draw a part of an image
on window (previously the whole image was drawn).
PaintImage(Drawable_t wid, Int_t x, Int_t y, Int_t xsrc, Int_t ysrc,
UInt_t wsrc, UInt_t hsrc);
where:
wid - a window where image is drawn
x,y - window coordinates where image is drawn
xsrc, ysrc, wsrc, hsrc - an image area to be drawn.

From Axel:
Implemented TGObject::SaveAs(const char* filename = "", Option_t* option = "")
allowing to save TGObject to a file using TImage.
The file type is determined by the extension of the filename parameter.
I.e. fFrame->SaveAs("myframe.gif").

From Valeriy Onuchin:
- add possibility to create an animated GIF file from canvas
(in both GUI and batch mode).
It's possible to Print pad into an animated GIF file by specifying
the file name as "myfile.gif+" or "myfile.gif+NN" ,
where NN is the delay for displaying subimages during animation in 10ms units.
If NN is ommitted the delay between subimages is zero.
for (int i=0; i<10; ++i) {
// fill canvas for context
// ...
c1.Print("file.gif+"); // print canvas to GIF file
}// end loop

From valeriy Onuchine:
- TImage, TASImage
o Change return type of Vectorize method from "void" to "Double_t*".
o Implement FromWindow method under X11. This method allows to
create "snapshot image" from any ROOT window or frame.
- config/Makefile.depend
Add dependency of libGuiBld lib on libGraf.
GuiBuilder uses internally TImage/TASImage class.
- GX11Gui.cxx
X11 error handler was slightly modified.
Many X11 errors lead to freezing X11 server and
did not allow debugging.
To prevent freezing, a "forced seg.violation" was added
to the error handler.
The usage of the new "feature" is the following:
0. run "gdb root.exe"
1. set "gDebug = (int)gVirtualX" - that activates the new error handling.
2. run application which has X11 errors.
On X11 error the application was stopped by the "forced seg.violation".
3. "gdb>bt" - backtrace the problem.
!!! A big list of changes in libGui initiated by gui builder development !!!
- TGButton.h, TGButton.cxx
TGButton class:
o SetDown methods removed from context menu.
o SetEnabled method of context menu changed to TOGGLE.
Setting fWidgetFlags was added.
- TGTextButton class

- TGColorSelect
o added to GuiBuilder widgets palette.
- TGComboBox
o new methods:

should be called by user.
o new methods:
void SetFont(TGFont *font);
void SetColor(Pixel_t color);
void SetAlign(Int_t align);
void EnableAlign(Bool_t on = kTRUE);
void UpdateStyleSize(const char *family);

From Valeriy and Ilka:
The last patch of Valeriy with some additional comments by Ilka:
- TVirtualX/TGWin32/TGWin32VirtualXProxy, TGQt new methods added
o unsigned char *GetColorBits(Drawable_t wid, Int_t x, Int_t y, UInt_t w, U
Int_t h)rns an array of pixels created from a part of drawable (defined by x, y,
w, h)n format: b1, g1, r1, 0, b2, g2, r2, 0 ... bn, gn, rn, 0 ..
Pixels are numbered from left to right and from top to bottom.
By default all pixels from the whole drawable are returned.
Note that return array is 32-bit aligned
o Pixmap_t CreatePixmapFromData(unsigned char * bits, UInt_t width, UInt_t h
eight)create pixmap from RGB data. RGB data is in format :
b1, g1, r1, 0, b2, g2, r2, 0 ... bn, gn, rn, 0 ..
Pixels are numbered from left to right and from top to bottom.
Note that data must be 32-bit aligned
- TGQt (*provided changes do not work; I cannot run rose_image.C tutorials under
tRoot because of SegV in:

From Valeriy:
TGPicture:
- fix deallocation autogenerated disabled pictures. That allows to fix
seg. violation after running $ROOTSYS/test/stress reported by Markus Frank.
An important comment was added to constructor
TGPicture(const char *name, Pixmap_t pxmap, Pixmap_t mask)
"both pixmaps pxmap and mask must be unique (not shared)"
- new method TGPicturePool::GetPicture(const char *name, char **xpm) added
that allows to create pictures from in-memory XPM array
Example:
#include "myicon.xpm" // contains static char** myicon {..} array
const TGPicture *pic = gClient->GetPicturePool()->GetPicture("myicon",
myicon);
TGButton:
- new method SetEnablled added which allows to activate/deactivate
enabled/disabled state of button
TASImage/TImage:
- Few new vector graphics methods added:
DrawCubeBezier, DrawStraightEllips, DrawCircle, DrawEllips,DrawEllips2
ToGray method, which allows to convert RGB image to Gray image
TImageDump:
- open circle polymarkers are implemented

From Valeriy Onuchin:
- TASImage class:
o new method GetImageBuffer is introduced. It returns in-memory buffer
compressed according to the image type.
Buffer must be deallocated after usage.
This method can be used for sending images over the network.
o new method SetImageBuffer introduced. It creates image from compressed
buffer. Supported formats:
PNG - by default
XPM - two options exist:
1. xpm as a single string (raw buffer). Such a string
is returned by GetImageBuffer method.
For example:
char *buf;
int sz;
im1->GetImageBuffer(&buf, &int, TImage::kXpm); /*raw buffer*/
TImage *im2 = TImage::Create();
im2->SetImageBuffer(&buf, TImage::kXpm);
2. xpm as an array of strigs (preparsed)
For example:
char *xpm[] = {
"64 28 58 1",
" c #0A030C",
". c #1C171B"
...
TImage *im = TImage::Create();
im->SetImageBuffer(xpm, TImage::kXpm);
o custom Streamer was implemented. That allows to save images in ROOT files.
Image's thumbnail is also saved into a file.
o galaxy_image.C tutorial is modified according to new saving schema.
o new demo file gallery.root added to tutorials. It contains thumbnailed
and browsable pictures produced by some ROOT tutorials.
o fix bug im TASImage::DrawRectangle methods. Thanks to Thomas Bretz
for reporting it.
- TKey class.
Possibility to save thumbnail/icon as XPM string along with object added.
Currently such mechanism is used for saving thumbnailed images.
- TGPicture. Platform-dependent code was removed. Now TGPictures
are created by TImage objects.
- TRootBrowser classes. Possibility to show objects with dynamically created
icons added.
- numerous bug fixes in libAfterImage library.

From Valeriy Onuchin:
- new method GetPicture added to TImage,TASImage classes
That allows to create TGPicture not only from XPM files but
also from png, jpg, gif, tiff files.
An example, of usage:
TImage *img = TImage::Open("rose512.jpg");
const TGPicture *pic = img->GetPicture();
TGPictureButton *btn = new TGPictureButton(parent, pic)
- TGPicturePool::GetPicture(const char *name, Pixmap_t pxmap) added
That allows to create TGPicture from given pixmap. For example, that will allow,
to create TGPicture from TPad.
- TGPicturePool::GetPicture(const char *name) return picture for supported
image formats xpm, png, jpg, gif, tiff
Now it's possible to create TGPictureButton, TGImageMap from files of these formats.
- default ROOT browser actions changed for png, jpg, gif, tiff files. That allows
to browse these file with TBrowser
